Inventario florístico de la comunidad lacandona de Nahá, Chiapas, México

Abstract

The Lacandon community Nahá is located at the north of the Lacandon rain forest, at the Municipality of Ocosingo, Chiapas; their vegetation preserves some areas with mature rain forest and the rest is subject to traditional diversified and intensified advantage. Results indicate that the preliminary vascular flora includes 118 families, 344 genera and 504 species, mainly in the rain forest. Ten species are listed in some risk category in the Norma Oficial Mexicana (NOM-059-SEMARNAT-2010). Trees are the more abundant life forms in the region, followed by herbaceous, epiphytes, and shrubs. Common names for 366 species were recorded, and some use for 239 of them. Twenty-five new records are presented for 22 species not previously reported for Chiapas, and three for México. The species richness and conservation status of the mature vegetation in the studied area highlight the importance for its conservation. Traditional knowledge of Lacandon people has maintained this diversity in spite of the constant developmental pressures by the human establishments surrounding the area.
